Adds "places" directory consisting of new moz-storage-based history
implementation. Use --enable-places to use this code instead of the Mork history implementation. This code is currently in active development, so some things are broken, notably all the UI which uses RDF. bug 266174 r=bryner This file was copied in CVS from the following location: mozilla/browser/components/places/public/nsINavHistoryService.idl Original committer: brettw%gmail.com Original revision: 1.1 Original date: 2005/11/08 02:25:22
